We have here another pretty, hardy, blue-flowered Ceanothus 
from California, discovered by Mr. W. Lobb, and communicated 
by the Messrs. Veitch, of Exeter and Chelsea Nurseries. It is 
one of the group whose leaves have three ribs, and therefore 
is far removed from our C. floribundus, Tab. 4806 of our last 
number. It has some resemblance to C. thyrsiflorus, Eschs., 
but there the branches are straight, erect, and angular, the leaves 
are much larger, and flowers paler-white in our specimens in the 
dried state; as it has also to C. divaricatus of Nuttall, from 
whom we have an authentic specimen before us, and other spe- 
cimens gathered by Jeffray (n. 1201), and by the officers of Fre- _ 
mont’s Expedition to California (n. 357),,and even from Mr. WwW. 
Lobb, all agreeing in having leaves with the margins quite plane 
and fringed with very minute glandular teeth : whereas our plant 
is remarkable for the reflexed margins (both in the wild and 
cultivated state), and the conspicuous glandular teeth. In other 
respects, it must be confessed, the two have a great affinity. 
The present is every way worthy of cultivation, and is quite gay 
with its pedunculated clusters of small but thickly-placed bright 
blue flowers, which are produced in June and July. :

terete, rather twiggy dranches, the young ones green and downy. — 
Leaves patent, alternate, rarely exceeding’ an inch in length, — 
generally bearing young leaf-shoots in the axils, on short petioles,
